$http_referer

[snappy]

Hi all

Say I link to a page (say test.php) in my website from my sitemap, is their a way that I can see, on test.php, that I was reffered from my sitemap ?

I tried to use this code in test.php :

<a href='$HTTP_REFERER'>Refered page</a>

But if I mouse over the link it only refers to http://www.mysite.com and not to
http://www.mysite.com/sitemap.php

Is their a way that I can do the later ?

You will have to pass the value, either with a request variable, or in a session. The HTTP_REFERER is set by the client and is completely untrustworthy (even if it did contain all the desired information).

Try echo-ing the $HTTP_REFERER value. That should work.

With register_globals turned off by default, I suggest you use $_SERVER['HTTP_REFERER'] instead of $HTTP_REFERER.

But like edwardsbc said it, it is totally unreliable ! Many browsers can be set up so they don't send referers... Also, it is easily changeable, so it is worth absolutely nothing for security...

use a little javascript code for it (not a js wiz but something like history.go(-1) might be wrong) if php doesnt work
